DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 and FIG. 2 show a schematic and dissected view of the present invention respectively. The protective apparatus for tablet electronic device of the present invention includes a receiving unit 1 and a protective cover 2. Receiving unit 1 is to clap or fasten the electronic device, and protective cover 2 is a foldable plate set. Protective cover 2 can be folded into a three-dimensional U-shape. To use the protective apparatus, receiving unit 1 is buckled to protective cover 2 so that the electronic device is wrapped by protective cover 2 for protective.

The following describes the details of each element of the structure.

The front surface of receiving unit 1 includes a large area plate surface 10. The edge of plate surface 10 is slightly curvy inwards so that the edge of receiving unit 1 ahs the resilience to be slightly push-open. In addition, the circumference of plate surface 10 forms a plurality of clappers 11, protruding from the level of plate surface 10. Plate surface 10 is the place for placing the electronic device, such as tablet PC. Clappers 11 are to clap the circumference of the electronic device. When electronic device is placed on plate surface 10, receiving unit 1 is slightly pushed-open and the resilience will allow clappers 11 to clap on the sides of the tablet PC to fasten the tablet PC. In the present embodiment, clappers 11 have a curvy shape and are located at the four corners of receiving unit 1. However, the number and the shape of clappers are not limited to the present embodiment. For example, the number of the clappers can be three, with one on each side of receiving unit 1 so that the tablet PC can be clapped on three sides.

As shown in FIG. 3, f the back surface of receiving unit 1 forms a protruding element 13 at the central area. Protruding element 13 is shaped as a cone. In other words, the diameter of protruding element 13 is the smallest at the joint with main body of receiving unit 1, and the diameter increases outwards. Also, protruding element 13 forms at least a slot 14, shaped to match other auxiliary apparatuses so that receiving unit 1 of the present invention can also be installed at other auxiliary apparatuses in addition to protective cover 2.

Protective cover 2 is a foldable plate set. When unfolded, protective cover 2 is a large area rectangular plate. Protective cover 2 can be folded into a three-dimensional U-shape. In the present embodiment, protective cover includes a first plate 21, a second plate 22, a third plate 23 and a fourth plate 24, connected in the above order, and foldable at the junction. The total area of first plate 21 and second plate 22 is similar to the area of fourth plate 24. Third plate 23 is smaller in size. When the plate set is folded into a three-dimensional U-shape, third plate 23 is the bottom side of the U. Other than plate-shape, third plate 23 can also be a flexible connecting element to enable folding of the remaining plates. To protect the electronic device, the inner wall of fourth plate 24 can be made of soft material, such as, cloth, foam, to avoid abrasion to the electronic device.

Furthermore, first plate 21 includes a buckle seat 25, partially extending to second plate 22. When the junction of first plate 21 and second plate 22 is folded, buckle seat 25 is lifted from the level of second plate 22. Buckle seat 25 is shaped as C clip. The vertical size of the trench is narrow at the top and wide at the bottom, that is, as a cone trench. Protruding element 13 of receiving unit 1 matches the shape of buckle seat 25 so that protruding element 13 can be placed from the opening of the radius direction of buckle seat 25, and cannot slip from buckle seat 25 from the axis direction once placed inside. Buckle seat 25 further includes resilient clip 251 to enhance the tight holding when clipping. In addition, receiving unit 1 can pivotedly rotate around the joint of protruding element 13 and buckle seat 25 when budded.

To use the present invention, electronic device 3 is fastened to receiving unit 1 and receiving unit 1 is buckled to protective cover 2. As shown in FIG. 4, when protective cover 2 is folded into a U-shape, the circumference of electronic device 3 is wrapped and well protected. When protective cover 2 is unfolded, the operation on the touch screen of the

Electronic device is convenient. For video viewing, as shown in FIG. 5 and FIG. 6, second plate 22, third plate 23 and fourth plate 24 of protective cover 2 are folded to form a ∠ shape. Then, the bottom edge of receiving unit 1 engaged to first plate 21 is placed on fourth plate 24 so that the back of receiving unit 1 is supported by protective cover 2 to stand with a tilt angle. Because protruding element 13 can rotate around buckle seat 25 of first plate 21, the user can easily adjust the viewing mode to either landscape (FIG. 5) or vertical (FIG. 6) mode.

Furthermore, because receiving unit 1 and protective cover 2 are detachable, receiving unit 1 can be detached from protective cover 2 and attached to other auxiliary support apparatuses via slot 14 of protruding element 13 of receiving unit 1 when used in vehicle or other locations. In this manner, the present invention can be applied to a wide range of uses.
